Example Embodiment
[0009] Such as figure 1 Among them, the powdery explosive additive uniform feeding device includes a quantitative screw machine 1, and a cone nozzle 2 arranged at the discharge port 3 of the quantitative screw machine 1. The discharge port 3 of the quantitative screw machine 1 passes through the sealing assembly 4 and the cone nozzle 2. Connected, the cone nozzle 2 is provided with a high-pressure air intake device 5; there are two high-pressure air intake devices 5, and the cone nozzle 2 is horizontally symmetrically distributed.
[0010] The working principle of the invention: when the powdery explosive additive is added, the quantitative screw machine 1 quantitatively transfers the powdery explosive additive into the cone nozzle 2 through the discharge port 3, and at the same time passes the high pressure air through the high pressure air arranged on the cone nozzle 2. The air inlet device 5 is input into the cone nozzle 2, and the powdery explosive additive in the cone nozzle...
